Concurrency test now passes

Restructured the queue handling to isolate the blocking stream.Recv(), and found a seemingly random block point somewhere. After experimenting with the sizes of the long messages generation, it was determined that messages over 4kb are getting stuck in the gRPC packet handling code somewhere. Nothing that can be done about it, but just needed to fully isolate where the problem was so I could finally call the damn queue implementation done.
